EYEGLASSES.

Specification of Letters Patent.

Patented Aug. 24, 1915.

Original application filed February 14, 1908, Serial No. 415,808. Divided andthis application filed May 11, 1912. Serial No. 696,590.

To all whom it may concern Be it known that I, LEO F. AM, of Al-. bany, in the county of Albany and State of New York, have, invented certain new and useful Improvements in Eyeglasses; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming a part of this specification, and to the reference-numerals marked thereon.

My present invention relates to eyeglasses and particularly to eyeglasses of the finger piece type and it has for its object to producea simple, durable and efficient mounting of this nature in combinatlon with a stud construction, namely, one 1n which the'bridge is separate from and interchangeable with respect to the lens attaching portion.

Further objects are to provide an economical structure that may also be con veniently manipulated and to meet other requirements of a practical mounting.

To these and other ends the invention con sists'in certain'improvements and combinations of parts, all as will be hereinafter more fully described, the" novel features being pointed out in the claims at the end of the specification. V

lnthe drawings: Figure 1 is a front elevationof an eyeglass constructed in accordance with and illustrating one embodiment of my invention; Fig. 2 is a topplan view thereof; Fig. 3 is a bottom plan view; Fig. 4 is a transverse central .section through the bridge, showing one of the guard levers in side elevation; Fig. 5 is a section longitudinally of the bridge taken substantially on the line 5-5 of Fig. 2, on an enlarged scale; Fig. 6 is a section taken substantially on the line 6-6 of Fig.5, and Fig. 7 is a detail perspective view of one of the guard levers and its spring. l I

Similar reference numerals throughout the several figures indicate the same parts. i This application is a division of my prior application entitled Eyeglasses, Serial No. 415,808, filed February 14, l908,which' parent application relates more particularly to the specific construction and arrangement of the guard levers and their springs, irrespec tive of the general nature of the support. Therefore, the same parts aresh'own here only in an ancillary capacity and will be but briefly described hereinafter.

In the practice of my invention, as shown in the present embodiment thereof, I provide a rigid, forwardly inclined, arched bridging portion 1, and a lens attaching portionat either end thereof that may, in general, be constructed very much as .usual to comprise lens clips Qand edge straps 8. The bridge, however, is made separate fromand is detachable with respect. to each lens attaching portion for the purpose of interchangeability, in order that particular bridges may be supplied for noses of par.- ticular proportions, as is known in the art, and to these ends one of the parts, preferably the lens attaching portion, is in each instance formed with substantially horizontally arranged seats, which in thi instance, are in the form of boxes 4 opening toward each other to receive substantially horizontally arranged attaching arms or ends 5 extending outwardly from the other member, namely the bridge, Each seat or box is held to an attaching arm by an upright or vertically arranged fastener 6 which preferably is provided with an intermediate shoulder. 7, a screw threaded portion 8 on one side of the shoulder and a bearing portion 9 on the other side of the shoulder-Q The screw threaded portion passes, preferably freely, through the arm 5 on the bridge in each instance and engages the screw threaded walls of an opening 10 in the bottom of the box 4, this end'of the fastener also projecting be yond or below the box for a purpose hereinafter described. As the fastener is applied,

the shoulder 7 thereon draws the attaching arm 6 of the bridge and the seat or box together, and to'this end the opening in the upper wall of the box, which is in alinement with thelower'opening 10, is enlarged to permit the shoulder to preferably directly engage the attaching arm. The bearing porwardly and rearwardly and finally merges above referred to, are arranged to extend pieces 14: at their forward ends. At an intermediate point, each is provided with a notch oropen bearing 15 adapted to cooperate with the bearing portion 9 of thefa'stener 6 and these and adjacent parts are so proportioned as to permitthe guard lever, in each instance, to be applied to or removed from its support in a lateral direction by tilting it and sliding it under or from beneath the head 11 of the fastener in a manner fully described in several of my prior applications and patents, so that in the present embodiment of this invention it is not required to remove the fastener and release, even partially, the bridge, and lens attaching portions in order to release or remove the guard lever. The finger piece 14 of each lever is, in the present instance, constituted by a loop in the material of the lever. formed by an arm that proceeds down-- into the outer convolution of a fiat spiral coiled spring 16 which is thus formed integrally therewith in thi embodiment. There is one of these springs, of course, for

each guard-lever that operates to position its nose engaging portion against the nose and aside from being carried by its guard lever and detachable therewith, it is centered against lateral movement by the lower or reduced projecting end of the fastener 6 before described, as clearly shown Fig; 5,

' the spring being on the opposite side of the supporting portion of the mounting from the guard lever. The inner end 17 of the spring is extended from the inner convolution across the coil and cooperates with'a stationary part provided, in the present instance,by a depending hook or projection 18. Of course, I do not wish to limit myself to the use of the particular spring and guard, shown in my prior application, in

connection with, the supporting structure forming the subject matter of this applicationas. other springs and guards of a widely different character may be employed,

with good results, in such stud construction. Such details are described herein only for the purposeof showing a complete eyeglass and one mode of practising the invention here involved. I

II claim as my invention: 1. Inan eyeglass mounting, the combination with a lens attaching device and a bridge, of a connection between them embodying a substantially horizontal seat on one of said-parts, a substantially horizontal arm on the other of said parts and a fastener having a shoulder intermediate its ends engaging one part for drawing the parts together, a screw portion on one side of the shoulder threaded into the other part only, and a bearing portion on the other side of the shoulder, and a finger piece nose guard lever turning on the bearing.

2; In an eyeglass mounting, the combina tion with a bridging portion and a lens attaching device, of means connecting them comprising an arm on one of said parts, 'a horizontally arranged box on theother of said parts, and a screw fastener having a shoulder engaging "one part and threaded into the other part, only, for drawing the box and the arm together and also having a bearing portion projecting from one side of the box and a head; anda finger piece guard lever mounted to turn on the bearing portion in engagement with the box and the head. I V

3; In eyeglasses, the combination with a tener threaded into one of said partsto exlens attaching device'and a bridge, of a fastend freely through the other and, having a i shoulderengaging the outer side of the lat j ter, and a finger piece nose guard lever turning on the fastener beyond the shoula der.

4.1n eyeglasses,- the combination with a lens attaching device and abridge, of a fastener having a reduced portion threaded into one. of the parts and extending freely through the other and. having its enlarged portion bearing against the latter'and pro jecting outwardly beyond the parts-and terminating in a head,of a nose guard turning tween the latter and one ofthe firstmentioned members, i
